Oil-free or oil-lubricated rotary screw air compressor? This guide explains how oil-free compression works, what ISO 8573-1 Class 0 really certifies, and how to choose between the two technologies for food, pharmaceutical and electronics production — without over-specifying or over-paying.

This guide is written for overseas procurement decision-makers, plant managers, and technical engineers evaluating low-pressure screw air compressors for textile manufacturing. It explains why standard 7–8 bar compressors are the wrong specification for most textile applications, how low-pressure PM VSD technology delivers 25–40% energy savings, and what air quality standard (ISO 8573-1 Class 2.4.2) is required for air-jet weaving. It covers the specific procurement questions that determine whether a compressor will deliver consistent pressure stability at the loom, and provides a TCO framework for evaluating the real cost of ownership over 10 years.
